Another obj ect ofthe invention is the provision of a vibrator of this character wherein the action thereof causes all air in the liquid -to rise to the surface and the liquidto freeze uniformly, the vibrator being ofnovelform and is readily installed in an apparatus for freezing liquids.

A. further object of the invention is the provision of a vibrator ofV this character which is extremely simple in its construction, thoroughly reliable and eiiicient in operation, and inexpensive to manufacture.

The' invention will be best understood from a consideration of the Vfollowing detailed description, taken in connection with the accompanying drawing forming part of this specification, with the further understanding that while the drawing shows a practical form ofthe invention, the latter is not confined to any strictV conformity with the showing of the drawing, but may be changed and modied so long'- as such changes andmodiiications come withinthe scope of the appended claims.

In the accompanying drawing Figure 1 is a vertical sectional elevation of a liquid freezing apparatus showing the vibrator attachment constructedlin accord- Y Patentdltar;lL-lgf..

adaptedV for constainngfV a' "noncongeaalitble liquidi capable of being: cireul'atedrthercint i the tank being of any approved construconeorfirore receptacles or cans B adapted for containing liquid to be frozen, for example, ice cream. The receptacles or cansB are vertically supported in any suitable manner rigidly within the tank and are preferably slightly elevated above the bottom thereof so that the liquid of noncongealable form may freely circulate about the same for the freezing of the contents` thereof.

Mounted at the top or near the same in the tank A between Yadjacent receptacles orY cans B is a fulcrum or trunnion bearing 5V Vpreferably of the form shown in Figs. 1 and 2 of the drawing, the bearing being designed to support a vibrator hereinafter fully described.

YThe vibrator comprises avr pendulum or oscillatory rod 6 which extends downwardly tieni-.1 anelli remevatly suspender therein isf Y between the receptacles or cans B and mayV Y Vbe of any desirable length, the'lower end of said pendulum or rod 6 being formed with a hammer or'striking head 7 which on the oscillation of said pendulum or rod strikes alternately the sides of the receptacles orY to the surface and the liquid will be caused to congeal very rapidly, thereby eliminat-V ing the white or opaque cakes of ice within the frozen liquid such as ice cream, whichV is very objectionable. Y

The pendulum or rods 6 extend upwardly beyond the top of the tank A. and are piv- Votally connected to a master or connecting rod 8 which is Yreeiprocated from any suitbeen omitted.
